>> “Baptism is how your sins are washed away and you receive the Holy Spirit. Peter says it saves you!” <<
.
That is falsehood on both counts. God’s word says no such thing, nor does Peter preach that lie.

>> “The Nicene Creed is evidence of what the Church has taught for 2,000 years” <<

The Church teaches nothing but to read the word of God. The “catholic church” is not even a part of the Church; it is an invention of evil men that denies the word of God and replaces it with vile creeds.
